A superhero (sometimes rendered super-hero or super hero) is a type of hero or savior possessing extraordinary talents, supernatural phenomena, or superhuman powers and dedicated to protecting the public. A female superhero is sometimes called a super heroine (also rendered super-heroine or super heroine).
While the word "superhero" itself dates to at least 1917, the term "Super Heroes" is a typography-independent descriptive USA trademark which is co-owned by Marvel comics
By most definitions, characters do not strictly require actual supernatural or superhuman powers or phenomena to be deemed superheroes although terms such as costumed crime fighters or masked vigilantes are sometimes used to refer to those such as Batman and Green arrow without such powers who share other superhero traits. Such characters were generally referred to as "mystery men" in the Golden age to distinguish them from characters with super-powers.
Some superheroes use their powers to counter day-to-day crime while also combating threats against humanity by Super villains, their criminal counterparts. Often, one of these super villains will be the superhero's archenemy. As well, some long-running superheroes, such as Superman, Batman, Spider man and X-men, have a rogue gallery of enemies. As well, superheroes sometimes will combat such threats as aliens, magical entities, American war enemies such as Nazism or Communism, and godlike or demonic creatures.
